DNA Mutation Causes Heart Disease in People of European Descent

WASHINGTON (Reuters) - A treasure hunt for genes has found that up to three-quarters of people of European descent have DNA that raises their risk for heart disease -- and these genes are close to a stretch of DNA linked to diabetes.
The findings, made by two independent groups of researchers, may help explain why so many people have heart disease even if they do not have clear risk factors such as smoking, high cholesterol or high blood pressure.
